Steel comes in many varieties and has its specific features and qualities. Examples of steel are aluminum steel and stainless steel.
Aluminum steel is more economical the hence that the cost of production for aluminum steel is low when compared to the cost of production of stainless steel; stainless steel is stronger and durable when compared with aluminum steel.
Stainless steel can easily change its shape or form when exposed to heat because it has a high thermal expansion. This is unlike aluminum steel.
When it comes to rusting aluminum can rust when the aluminum coat is broken, but stainless steel doesn't rust because of the presence of chromium.
Examples of products made from aluminum steel are space heaters, grills, water heater, furnace; on the other hand, examples of products made from stainless steel are storage tanks, kitchen utensils and cookware, etc.
